摘　　要：通过甘蔗旬生长高度递增量与气象因子的关联度及因子筛选分析，在气温日较差很大的金沙江干热河谷，地面最低温度对甘蔗生长速度制约最大；夏季旺长期，生长速度还与前３候降水量密切相关；而与日照的关联度最小。因此，在我国西南横断山区干热河谷地区的农业综合开发中，不仅要看到这一区域的光照条件，重视农业灌溉条件的改善，更要重视温度条件对农业生产的影响。The analysis of factor screening is done by the correlation between the increment progressively of ten-days growth height of sugarcane and meteorological factors. In the dry-hot river valley of Jinshajiang with very great daily range of temperature, the influence of surface minimum temperature on the growth speed of sugarcane is maximum. During rush growth period in summer, its growth speed has also close correlation with previous three pentad's rainfall amount, but its correlation with sunshine is minimum. Therefore, when making agricultural comprehensive exploitation of dry-hot river valley of Hengduan mountain area in Southwest China, we not only consider the sunshine condition and pay attention to the improvement of agricultural irrigation condition but also pay great attention to the influences of some climatic features such as temperature condition on agricultural production.
